Indianapolis - Three audio brands by the end of the year will offer a powered soundbar that uses H-PAS bass-extension technology to deliver bass down to 47Hz at -3dB without the use of a separate subwoofer.
The three companies are Atlantic Technology, H-PAS inventor
, and direct-to-consumer audio supplier Outlaw Audio, said Atlantic president Peter Tribemen at the CEDIA Expo. Tribeman also operates Outlaw Audio.
H-PAS, which stands for Hybrid Pressure Acceleration System, is promoted as delivering targeted bass performance with 50 percent smaller cabinets, smaller drivers and lower costs. In a soundbar, it would eliminate the need for a separate subwoofer, making it appealing to more households and suitable for use in secondary rooms in a home, Tribeman said.
Besides improving the sound quality of flat-panel TVs, the system performs strong enough to serve as a music-playback system, including playback of music streaming services accessed by smart TVs, he said.
In revealing more details about Atlantic's planned soundbar, Tribeman said he expects to price Atlantic's model between $500 and $600, depending on currency fluctuations. The two-channel system, rated at 2x40 watts, features Trident technology to deliver virtual surround sound from two-channel Dolby Digital and PCM sources and 5.1-channel Dolby Digital sources. The soundbar also includes Dolby Digital 5.1 decoder.
The driver complement consists of two 4-inch drivers and two 0.5-inch tweeters.
The wall- and table-mount speaker features one optical digital input, two RCA analog inputs, and a front minijack input. The company might add a second digital input, Tribeman said. A subwoofer output is included if someone wants to further deepen bass response.
The soundbar comes with an IR remote whose codes can be learned by learning remotes.
Atlantic is licensing the technology to other, combines elements of bass-reflex, inverse-horn, and transmission-line speaker technologies to pressurize and accelerate low frequencies. H-PAS is promoted as breaking what the companies have called "the iron law of loudspeaker design," which law states that among three key goals of speaker design -- deep bass, compact enclosures and good efficiency -- two must be selected at the expense of the third.
